FOR SATELLITE ANTENNAS:
SAFETY CHECK-OUT
1. Check the area of your repair for unsoldered or poorly-
soldered connections. Check the entire board surface for
solder splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground
straps, and mounting hardware have been replaced. Be
absolutely certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recom-
mend the replacement of any such line cord to the
customer.
7. Check the B+ and HV to see if they are specified
values. Make sure your instruments are accurate; be
suspicious of your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
leakage using one of the methods listed.
Figure 1. Using an AC voltmeter to check AC leakage.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any exposed
metal part having a return to chassis, must not exceed 0.5
mA (500 microamperes). Leakage current can be mea-
sured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229
or RCA WT-540A. Follow the manufacturers’ instructions
to use these instruments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means
of a VOM or battery-operated AC voltmeter. The “limit”
indication is 0.75 V, so analog meters must have an
accurate low-voltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of passive VOMs that are
suitable. Nearly all battery operated digital multimeters
that have a 2 VAC range are suitable. (See Figure 1)

Problem What you can do
Poor picture quality or no picture • If you are receiving only a few stations, (only 2 or 3 channels for
example), call your service provider to have your programming
activated.
• Some pay per view programs may be protected by Macrovision
®
copy protection at the discretion of the copyright owner. You
may want to connect the Digital Satellite Receiver directly to
your TV.
• Check the connections to your TV and other equipment
(see pages 7–13).
• Make sure that your TV and other equipment are set to the input
sourceto which you connectedyour Digital Satellite Receiver, for
example, channel 3 or 4, Video 1 or 2 (see pages 9–10).
• Check the Satellite Dish Antenna’s signal strength (see page 23).
• Make sure the RG-6 coaxial cable is properly connected to the
Satellite Dish Antenna.
•IfthecabledistancebetweentheSatelliteDishAntennaandthe
Digital Satellite Receiver is more than 100 feet, you must use the
Sony Amplifier EAC-DA1.
• Make sure your Access Card is inserted correctly (see page 13).
• Move any antenna cables that may be directly above your Digital
Satellite Receiver.
• Change the setting of the CH3/CH4 switch on the back of the
Digital Satellite Receiver. This could improvepicture quality only
if you are using the UHF/VHF IN jack of the Digital Satellite
Receiver to connect a local TV antenna or cable company service.
Poor picture quality or no picture when
it rains or snows
• Heavy rain or snow may degrade the strength of the signal
coming from the satellite to your Satellite Dish Antenna. To limit
any negative effects during degraded conditions, make sure that
your professional installerhas aimed your Satellite DishAntenna
so that you are receiving a high signal strengthlevel (see page 23,
or refer to your Satellite Dish Antenna Installation Instructions).
You cannot turn on the unit • Make sure that the AC Power Cord is plugged in (see page 13).
• If the AC Power Cord is plugged in, unplug the AC Power Cord,
wait a few minutes, then plug in the AC Power Cord again.
You cannot access a program • Make sure you subscribe to the station you are trying to access.
Your service provider can tell you to which stations you
subscribe.
• Make sure the station you are trying to access is not set to be
skipped (see pages 50–51).
• Make sure the system is not locked (see page 58).
• Use the Program Guide to access the station (see page 37).
• Press the SAT FUNCTION button on the remote control before
you select a channel (see page 20).

You cannot order a pay per view program • Make sure your Digital Satellite Receiver is connected to a
telephone line (see page 8).
• Make sure the system is not locked (see page 58).
• Use the Program Guide to access the station (see page 37).
• If the message “Purchase information not available” appears,
youmustcontactyourserviceprovidertoordertheprogram.
• Your Access Card may be full. If so, contact your service
provider.
•Itmaybetoolatetoordertheprogramyouwant.Ifso,checkfor
other show times (see page 45).
You cannot find the station of the pay per
view program that you ordered
• See “Checking Pay Per View Purchases” on p age 59 to get
information (station, start time, etc.) about programs that you
have ordered.
You cannot cancel a pay per view order • You cannot cancel pay per view orders that you have watched.
Contact your service provider for details.
The program highlighted in the Program
Guide does not appear
• Highlight and select the program. Although the program you
highlight appears in the Media Window display, you must press
the button to complete your selection (see page 37).
You cannot see any Favorite Stations • Set up your personal Favorite T itles before you try to use the
Favorite Stations guide (see page 41).
Locks & Limits feature not working properly • Make sure that the Spending, Rating, Pay Per View, and Stations
Blocked are set as you want them (see pages 53–56). Then, make
sure that the system is locked (see page 57).
You cannot access the Locks & Limits screens • The system must be unlocked before you can make changes to
the Locks & Limits (see page 58).
You cannot unlock the system • Make sure that you entered the passcode correctly. If you have
lost or forgotten your passcode, contact your service provider.
Language of audio track is incorrect or audio
track is not available
• Check the default language setting. The program provider may
not broadcast all of the languages in the Default Audio pop-up

function, check that the RF Antenna is connected correctly
(see page 12).
• SAT-A55 model only: Make sure that t he remote control and the
Digital Satellite Receiver are both using the same security code
(see page 33–34).
Audio noise • SAT-A55 model only: If you connect the DIGITAL OUT jack to
equipment that is not Dolby Digital compatible, set the Dolby
Digital option to “off” (see page 64). Not all optical jacks on
audio systems are Dolby Digital compatible.
